Way too gorgeous!!! I love GFG!!! I've quilted 3 of them....
You need more pins going thru the flowers. You only seem to have pins on the white..Think about adding at least 2 more pins per flower. It's almost like you can't pin too much - it helps keep things from shifting.
Great idea to try various frames if possible. When you start quilting - start in the middle and work your way out in all directions. Can't wait to see!
